CAST-METAL SIDE FRAME `FOR CAFFTRUCKS. v

Specicationiof Letters Patent.

Patented Sept. 25, 1906.

Application filed October 3'()J 1905. Serial No. 285,156.

To all whom, it may concern:

Be it known that I, ETHAN LDoDDs, a citizen of the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain newiand useful Improvements inCast-Metal Side Frames for Car-Trucks, of which the following is a specification.

Aside frame for a car-truck With detachable pedestal portions so constructed that by disconnecting th'e pedestal portions from the main body of the side the axles and journalboxes may be removed therefrom without jacking or lifting up the truck or the car forms the subject-matter of my present invention.

Another feature of my improved side frame is the facility with which the same may be repaired in case its ends become damaged, and, furthermore, since my new form of truck side is made up of a number of parts it may be more easilyhandled When the truck is being assembled than one which has all the parts integral.

In the accompanying drawings I have illustrated two embodiments of m invention, like reference characters on allrthe figures referring to the same parts throughout.

Figure 1 is an elevation of a side frame for a car-truck embodying my invention. 2 is a horizontal section of a portion thereof on the line 2 2 of Fig. 1. Fig. 3 is a vertical section through the right-hand pedestal portion on line 3 3 of Fig. 1. Fig. 4 is a partial plan'view of the side frame shown in Fig. 1. Fig. 5 is an elevation of a modified form of my invention. Fig. 6 is a plan view of the same, and Fig. 7 is a section on line 7 7 of Fig. 5.

The side frame illustrated in Figs. 1 to 4,l

inclusive, comprises a main plate or web portion 10, having integral top and bottom flanges 11 and 12, res ectively, extended outwardly from both sidJes of the plate portion 10, each end of the latter being provided with flanges or enlargements 13, recessed at 14 from top to bottom on their end faces. Integral vertical ribs 15 unite the top and bottom flanges 11 and 12 on both sides of plate or web 10, and inclined inte ral Vflanges 16 and 17 on each side of the pIate connect the junctions of lower flange 12 and the outermost ribs 15 to the end enlargemonts 13 and top flanges 1'1, respectively.

Fig..

' At the ends of its lower edge flange 12 is equipped with integral downwardly-extended lips 18, between which fit tongues 19 of the end pedestal members described hereinafter. Each end enlargement 13 is provided with a shoulder or seat 20, on which rests a small lug 21 integral With the upper part of the above-mentioned pedestal member; top tie-plate 22 may be riveted to the top flanges 11 of the sides to connect the latter, anda similar bottom plate 23 for the same purpose may be riveted to the lower flanges 12, while rivets 24 fasten the transoms (not shown) to the side frames. At each end the main plate or web portion 1() `is provided with a U-shapedpedestal member 25, the limbs of each of which rest upon the top and bottom surfaces of flanges 11 and 12, res ectively, each edestal member being supied with a hol ow spring-cap 26 and with inner and outer marginal flanges 27 and 28, respectively, extended outwardly from each side of its web portion 29 and connected at intervals by ribs 30. The pedestal member 25 is also supplied with an additional strengthening-rib 31 on each side substantially arallel to the outer flange 28. The upper inner portion of each pedestal member 25 has a horizontal shoulder 32, upon which rests the head 33 of a bolt 34, passing through apertures in the limbs of the U-shaped member 25 and through the recess 14, nuts 35 at its lower end securely holding the parts together. This bolt clamps the edestal member to the plate portion 10, wh1 e two bolts 36 passing throughholes in the upper flange 11 and in the end portion of the pedestal member with its nuts 37 resting againstshoulders 38, provided for that purpose, securely hold the member to the body portion 10 of the side frame. It will be ap arent that bolts 34 clamp the pedestal mem ers firmly to the main portion 10, while the bolts 36 prevent its longitudinal movement on the same art.

The three arts of the frame of the s ape shown in the rawings may be cast and bolted together, as illustrated. By removing the bolts the'end pedestal members may be disconnected, so that the axles and their journal-boxes can be readily and expeditiously removed from the side frame Without lifting the main plate portion 10.

.In Figs. 5, 6,l and 7 I have illustrated a ICO which form guides for the journal-boxes, are

provided. at the ends of the plate portion 40, the upper corners of the latter being inclined at substantially forty-five degrees and supplied -on both sides with a ange 46, notched' at 47 to receive the tongues48 of the pedestal portions described below. Parallel to the marginal flanges 46 are ribs 49, connected to.

the latter by ribs 50 on both sides of plate 40, ribs 49 joining the l end L and top flanges. Each end pedestal portion 51 has an integral hollow spring-cap 52, a vertical ange 53 forming the outside guide of the journal-box and a main web portion 54 supplied along its top and part Way down its side with a marginal flange 55 on both sides and a parallel intermediate flange 56 spaced a short distance therefrom and connected thereto and to the spring-cap portion by ribs 57. The inner end of each pedestal member is inclined so as to rest upon flange 46 with the tongue 48 fitted inthe groove 47, thereby positioning the parts and holding them in place while being bolted together, the pedestal members being held'to the main portion 40 of the side frame by U-shaped bolts 58 passing through apertures in the broad flange 59 of the pedestal portion and apertures in the flanges 46 and 49 of the plate 40, nuts 6() on the ends of the bolts holding the parts firmly together. It should also be noted that each flange 59, of which there-is one on each side ofthe pedestal member, has a rounded projection 59, adapted to fit the curvature of bolt 58 and form aseat therefor, and thateach flange 59 is recessed at 59h, leaving a thin web between the two opposite recesses.

The lower ends of the pedestals are- `equipped with yokes 61, bolted thereto,

which sustain one or more bolts 62, the function of which is to retain the journal-boxes and axles in place if the car becomes upset.

This ypatent is intended to embrace only so much of the disclosure made herein as is covered by the claims.

I claim- 1. A side for a car-truck including a eentral plate having a flange and a pedestal member detachably secured to said flange by one or more bolts passing through said pedestal member and flange only, substantially as described.
